dotted lines in Fig. 4. After the tripper has ASi() 4 are connected by switch tracks 14 and 15.

track 14.l The filled cars canthen be; drawn over the switch track 15 and attached to the entire number of cars 0 have been filled. During the iilling of these cars the tripperS may make a number ot trips to and tro i tolerably high speed or it may be propelled slowly so that a single movement of the trip'- per in one direction only is suiiicient to ett'ect the iilling of all the cars in the train. To avoid dropping the excavated material betWeeii the ends of the cars 9 as 'the trippei passes frfnii car to car,V it is desirable to provide a discharge chute 11 iaith some sort ot closure whereby the iioiv of material through the chute may be interrupted `While the tripper passes from one car to the next. To this end7 I provide a hinged section 12 at the lower end of the chute 1 1 and a gravitycatch 13 by which the hinged section of the chute may be held in the position indicated in passed 4from one car to the next, the operator can 'easily release the pivoted section ot the chute by raising the catch 13 'and the delivery of material can be instantly.renewed.

After the iilling oi the cars Q ,of the train, an engine can be attached to the rear extremity of the train and the ears can be quickly removed from. the section of track adjacent to the excavating apparatus, thus leaving this'portion of the track open for another train. To tacilitate therenioval ot the train of loaded cars and its replacementl by a train of empty cars, the tWo tracks 1 and It two engines are available, one of them attached to the train of empty cars 9a may be standing on the track 1 in :position to beV moved up behindl the excavating apparatus as soon as the iilled cars 9 aie hauled ont ovei' the switch track 14 ai-id on to the track 4. 1f only one engine is available, the v,cars 9% may be brought int-o the osition shown and the engine may then be etached, brought on to the track 4 over the Switch track 15 an'd then again on to the track 1 between the filled ears and empty cars bytravel4 over the switch o n to the track 4 over the switch track 1.4 and the engine can 'be returned to the track 1 train of empty cars preparatory to moving it into position to receive excavated' material from the conveyer. Whether'one or tivo enginesbe used, the timerequired to replacetlie .filled carswith eiiiptycars'is 'very slioi't` and, ifthe receiving hopper 10 be of proper capacity, the operation ot' the excavating apparatus need not be interrupted While the change of cars ismade. Of course, however, When a change of carsis in progress", the discharge of-niaterial from the conveyer must be stopped, and it is desirable that the operation ofl the conveyer be stopped While the loaded cars are being replacedl-JW empty ones. This is preferable tothe provision of a storare,

age hopper upon the' tripper andthe continees tied operation of the conveyor ivhen Vthe tripper isnot actually delivering material to the cars.

While 1 have shown a train ot iive cars for receiving the excavating material and have illustrated a conveyor ot corresponding length, i't is obvious that the length ol' the train oi'A vcars and ot' the conveyor may be-inci'eased or diminished as desired. 1t will also be noted that thesupports of the conveyor, being carried on wheels Which preferably rest upon track rails, the ci'iiiveyer andv the excavating apparatus can be advanced without dillieulty. as the work otl excavation is carried forward, and, when it is desired to shift t-lie position of the excavating apparatus laterally, the con'- veyer can be shifted at the saine time and in similar manner by simply relaying the track upon which it stands. By shifting the con- -veyer'to track tand placing the excavating apparatus on track 2, the ri ngc of' operation et the excavating 'apparatus can be altered as indicated by the broken lint` in Fig. 1.

Having thus described my invention, what ih cglaini as .new and desire to secure by Letters VPatient is:

1. The combination with excavating apparatus, ol a conveyer adapted to receive material Jfrom the excavating apparatus, and means for delivering material troni said conveyei to cars adjacent to said conveym'.l

2. The combination with excavatingapparat-us, oi' a receiving hopper into which said excavating apparatus is adapted to deliver, a conveyor on to which Said receiving hopper discharges, and means-for discharging material `from conveyer to cars adjacent to said conveyenl 3. The combination with excavating apparatus, ot a conveyer to which said exe-av aiingapparatus is adapted to deliver, said conveyer having a portion thereof elevated, and nieansior delivering material from the elevated portion of said'conveyer tecars adjacent to said conveyer.

44. -T he combination with excavating vapparatus, of a conveyer adaptedfito receive material `from said excavating apparatus, and traveling tripper or deliverer forsa-id convey Y i' whereby material may be delivered trom'said conveyer to cars standing alongmaterial from 'said excavating apparatus and a tripper or deliverei' i or discharging material from said conveyer into the cars arranged alongside oll said conveyer, said tripper having a discharge chute provided with y a closure, whereby the delivery ol' material through said discharge chute may be arrested When-said .tripper or deliverer is in transit from one car to another.
